The project consisted of over 4,000m2 of twinwall, lattice floor capping slabs and precast beam elements. A full design of the wall panels was carried out in house, accounting for impact forces from the waste sorting excavator buckets, along with various point reactions from gantries and mechanical sorting equipment.

Key design features included:

Walls of up to 7m in height

Cast in protective steel impact plates

450mm thick capping slabs

350mm thick twinwall

All installed within the structure, under very restricted lifting conditions
